Abstract (en)

[origin: WO2008054179A1] A method and apparatus for encoding/decoding an image using motion vector tracking are provided. The image encoding method includes determining corresponding areas of a plurality of reference pictures that are to be used to predict a current block by tracking a motion vector route of a corresponding area of a reference picture referred to by the current block; generating a prediction block of the current block by calculating a weighted sum of the corresponding areas of the plurality of reference pictures; and encoding a difference between the current block and the prediction block.
